Happy weekend, everyone. I recently did the charger modification for my M200 (opening machine / soldering couple of jump wires in place / reassembling - not a bad procedure at all), and it seems to be working fine. I'm wondering if NiMH batteries would work in it also or if there is a risk that they might either fail to charge or overcharge and get damaged. It would be nice to have the higher charge storage capacity, but currently I've got 1000 mAh NiCd cells installed.
Also wondering if there is a charger modification for the M102. I have done the one for my M100 (adding a small resistor per the procedure described in Bitchin100.com, http://bitchin100.com/wiki/index.php?title=A_Simple_Self-Charger_for_the_Model_100 ). Best wishes and thanks, Anthony
